"Reformat hard drive:Note: Reformatting the hard drive will delete all of your saved games and soundtracks. Go to "Settings" then "System Info". Then, press Y, Left Analog-stick Up, Left Analog-stick Down, X, A.
Does this work, and does it completely restore an XBox to factory state, such as reinstalling the default dashboard and settings, or does it simply clear the user data from the drive? Not that I need to do it, my XBox has a modchip so I can (and have) use Slayers (or Hexen) to reformat, but if this really works then it would be handy for people with non-modded XBoxes.
I'm not trying it, of course, in case it does work but doesn't give me a "Sure Y/N" chance to abort the operation, as my XBox is set up great and I don't want to have to go through it all again. I always thought it was strange than the stock XBox lacked a defragmenter and a format-and-reinstall-the-official-Dashboard feature since Microsoft's operating systems for the PC always allow this, so why not the XBox since it too has a hard drive.
